Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for an automobile rear seat (rear seat cushion) that is fixed to a cross member on the front floor of the vehicle by locking only the front side.

Conventionally, this type of seat A has a U-shaped stopper 1 hanging down from the lower front end of the seat A, as shown in Fig. 1.
(wire bent into a U-shape) is tool 1
1 is used to secure the front part of the seat A to the vehicle body B by tightening the screw 10 into the mounting hole drilled in the vertical surface of the cross member b. During this installation work,
Since a carpet is laid on the outer surface of the cross member b for purposes such as soundproofing and buffering, the mounting hole is covered by the carpet and the opening position is not visible from the outside. Therefore, it is difficult to confirm the position of the mounting hole, and the tool 11 must be used to tighten the seat in a narrow space, resulting in extremely poor workability when mounting the seat.

Note that there is a method for attaching the seat without using the tool 11, which is disclosed in Japanese Utility Model Application Publication No. 163830/1983. This is approximately U, which is elastically biased in the direction of opening outward from each other in the stop holes provided in the car body.
It has a structure in which a letter-shaped intermediate plate is installed, and a seat cushion frame is fitted and attached to this intermediate plate.
Therefore, since the seat cushion frame is attached to the intermediate plate made of a leaf spring, the intermediate plate swings under the load of the seat cushion in the longitudinal direction.
As a result, the seat cushion became loose, making it uncomfortable to sit on. In addition, because the seat cushion frame is inserted into an intermediate plate provided in a hole in the vehicle body that cannot be seen from the outside, the work efficiency of installing the seat cushion is poor, and it is necessary to improve the work efficiency. If the holes are made larger, the backlash of the seat cushion increases.

Therefore, the present invention aims to eliminate such defects of conventional products.

The gist of the present invention to achieve such an objective is to provide a cross member that constitutes the floor surface of the vehicle body and has a vertical surface for attaching seats, and a cross member that is attached parallel to the vertical surface on the outer surface of this cross member. A seat stopper, a bracket fixed to the outer vertical surface of the cross member parallel to each other with a gap for fitting the seat stopper, and a bracket protruding from a window hole provided in the bracket in the direction of the vertical surface of the cross member. The front part of the seat is fixed to the vehicle body by locking a seat stopper fitted into the gap between the cross member and the bracket with an elastic locking piece. It is. That is, the present application improves the workability of installation by locking the seat stopper on the outside of the cross member, and also provides a seat that is formed in the gap between the cross member and the bracket in parallel to both members. The seat is securely fixed to the vehicle body by inserting the stopper, and the load in the longitudinal direction of the seat is borne by the cross member and the bracket.

Embodiments of the present invention will be described below based on the drawings.

In the figure, A indicates a seat (rear seat cushion), and on the left and right sides of the front bottom of the seat A, substantially U-shaped wire stoppers 1 that are fixed to the frame line 7 that constitutes the seat A are vertically installed. . On the other hand, car body B
A locking piece 2 is attached via a bracket 3 to a position corresponding to the stopper 1 on the vertical surface _b1 of the cross member b constituting the floor surface of It consists of a side plate 3b extending from the edge and the lower edge and fixed to the vertical surface _b1 of the cross member b, and a front plate 3a.
are provided in parallel, the gap between the plate 3a and the cross member b is slightly wider than the wire diameter of the stopper 1, and the horizontal width of the plate 3a is formed to be slightly wider than the horizontal width of the stopper 1, so that the stopper 1 It is inserted into the bracket 3 in a fitted manner so that it does not move forward, backward, left or right. A window hole 3c is formed in the front plate 3a of the bracket 3, and a chevron-shaped locking piece of an elastic locking piece 2 (made of a leaf spring) is inserted inward from the outer surface of the window hole 3c. The stop part 2a is inserted and its lower end is fixed to the front plate 3a with a rivet 4 so that the front plate 3a exhibits springiness in the front-rear direction. Therefore, when the stopper 1 of the seat A is inserted into the bracket 3 against the elasticity of the locking piece 1, the curved lower end 1a of the stopper 1 is locked to the locking piece 1, and the stopper 1 is fixed to the seat A. 2 to 4). When the seat A is lifted upward against the elasticity of the locking piece 2, the locking state of the locking piece 2 is released and the seat A is removed from the vehicle body B.

The locking piece 2' shown in FIG. 5 is formed by bending the locking portion 2a' into a substantially right triangle shape to achieve a complete locking state, and one end 2b of the locking piece 2' is pulled outward. This structure allows the locked state to be released.

In the embodiment shown above (FIGS. 2 to 5), the stopper 1 is in a locked state and its front and rear sides are supported by the front plate 3a of the bracket 3 and the vertical surface _b1 of the cross member b. Therefore, the seat A is likely to come off due to the longitudinal load applied during a collision, sudden stop, sudden start, etc. In such a case, the longitudinal direction of the stopper 1 will be in the vertical plane of the bracket 3 and the cross member b.
Seat A cannot be removed because it is supported by b ₁ .

Since the present invention has the above configuration, it has the following advantages.

(1) The stopper can be locked to the locking piece of the cross member by simply pressing the seat, so the installation work is extremely simple and the workability can be improved compared to the past.

(2) Since the stopper is attached to the vertical surface of the cross member and is locked to the locking piece, one side in the front and back direction is supported by the cross member, and the seat can move back and forth due to the load applied in the front and back direction of the seat. can be regulated and their removal can be prevented.

(3) The locking state of the seat stopper can be released by lifting the seat upward, so it can be easily removed.

(4) Since the stopper is locked by the elasticity of the locking piece, there is no need to worry about the screw for fastening the stopper loosening and causing abnormal noise as in the past.

Further, since the stopper is attached to the outer surface of the cross member, the attachment point of the stopper can be seen from the outside, and the workability of the attachment can be improved.
